The premixed cold reaction CW chemical laser places the secondary injectors which input fuel and/or diluent in the exit walls of the primary nozzle. These injectors are acutely angled thereto and are arranged in rows and are further grouped therein where a first injector inputs a pure diluent, a second group of injectors inputs independently of a third group.

A combustor for a premixed cold reaction CW chemical laser, said combustor comprising: a combustion chamber, said combustion chamber containing reaction products forming heated primary gas having therein atomic species of an oxidizer, said combustion chamber directing said reaction products to an output plenum; a plurality of wedges positioned downstream of said output plenum to form a plurality of primary nozzles, each of said primary nozzles having an input section, a throat section, and an output section, said sections forming a supersonic nozzle to output said reaction products as a supersonic gas; a plurality of secondary injectors having supersonic jets therefrom, said secondary injectors being located on exit walls substantially parallel to the streamlines of said primary nozzles and located downstream of said throat section of said primary nozzles, said secondary injectors being arranged in substantially parallel rows in a streamwise direction, each of said rows having a plurality of said secondary injectors therein, said plurality of secondary injectors in a row comprising a plurality of groups of secondary injectors, a first group being proximal to said throat section and injecting a diluent, a second group of secondary injectors downstream of said first group and inputting a fuel therein, said secondary injectors being at an acute angle to said exit walls, said acuteness being in the downstream direction, said supersonic gas and selected products from said secondary injectors mixing in a cold reaction to from a pre-lasing product, lasing of said pre-lasing products being trigger by a bow shock resulting from the interaction of said supersonic gases from said primary nozzle and the supersonic gases from said secondary injectors in said exit walls, and means for inputting to said combustion chamber and said secondary injectors chemicals necessary to produce lasing action.
